The current pollution status and control technology of the Taihu Lake Basin, Jiangsu Province, China

Abstract

Non‐point source pollution contributes greatly to lake eutrophication. This article explores a) the pollution status of rural southern Jiangsu and the Taihu Lake Basin; b) non‐point source pollution control; and c) vein river non‐point pollution control. Our work concerns an earthworm ecology filter, a capillary infiltration ditch, rural solid waste treatment and reuse technology. The tower earthworm eco‐filter and capillary infiltration ditch technology for effluent COD_Cr, NH₃‐N, TN and TP meet the Environmental Quality Standards for Surface Water (China), Category IV.

Keywords:
